nevermind, the docs are just missing a step. you need to select your workdown from the dropdown at the top of the screen (the dropdown is empty initially so its not obvious its there at all)

ajgeiss0702OP•11/15/24, 2:35 AM

i was only able to get the profiler to work once (i tried 4 other times, all of the other times it just froze when i hit stop) and it didnt show anything interesting.

Is it possible that browser rendering is using a ton of cpu time somehow? That is skipped in dev since its not supported, so thats the only thing I can think of

steve•11/15/24, 3:23 PM

I wrote a koa adapter , would you use it.:cloudflare: https://www.npmjs.com/package/koa-cloudflare-workers-adapter

npm

koa-cloudflare-workers-adapter

Latest version: 0.0.1, last published: a minute ago. Start using koa-cloudflare-workers-adapter in your project by running npm i koa-cloudflare-workers-adapternpm i koa-cloudflare-workers-adapter. There are no other projects in the npm registry using koa-cloudflare-workers-adapter.

ajgeiss0702OP•11/15/24, 5:36 PM

I think i found the issue. For some reason, after some random point, fetch requests suddenly stop processing or something? I added some logic to cancel them after a few seconds and retry, and the new requests do the same thing

ajgeiss0702OP•11/15/24, 5:40 PM

anyone know why that might be happening?

ajgeiss0702OP•11/15/24, 5:49 PM

the simultaneous open connections limit comes to mind, but I didnt think I was hitting that.
then I went back and re-read the docs for that just in case, and I saw they recommended canceling bodies that I don't intend on reading to free concurrent connections. Trying that now to see if thats whats causing this somehow

i just set an environment variable in dev, and use things like if(env.dev)if(env.dev)

Burrito•11/15/24, 6:51 PM

I don't think that trims the code though, does it?

ajgeiss0702OP•11/15/24, 6:51 PM

i dont think so

Burrito•11/15/24, 6:52 PM

ESBuild has definedefine which will actually trim the code, but I'm not seeing a way to hook into that.

Burrito•11/15/24, 7:39 PM

Ah sounds like exactly what I'm looking for, thanks.

Burrito•11/15/24, 7:42 PM

Hmm, seems like you can also use definedefine in

wrangler.toml

wrangler.toml

. Is it possible to specify some that only apply for dev but not production, so that I don't have to type npx wrangler dev --define ...npx wrangler dev --define ... all the time?

Mozzy•11/15/24, 7:48 PM

I have max-age set to 60 on my response, yet in the browser I sometimes see this on the response. How come?

cache-control: public, max-age=14400, must-revalidate

cache-control: public, max-age=14400, must-revalidate

Mozzy•11/15/24, 7:53 PM

Maybe Chrome is interfering and setting it to 14400?

Mozzy•11/15/24, 8:03 PM

Happens in Firefox too. Is there some additional config on Cloudflare that could be causing this?

Mozzy•11/15/24, 8:05 PM

Ahh, I see that the zone is set to 4 hours. I'll try to remove that specifically for the api subdomain

Mozzy•11/15/24, 8:10 PM

ajgeiss0702OP•11/16/24, 3:32 AM

I got it!
At first canceling unused responses didnt seem to do anything, but then i realized there was a case where I was breaking a loop before canceling the body stream. Fixed that and now it appears to be working!

So basically, it was not a cpu issue like the error message said. Sounds like it was just timing out, and the deadlock prevention was not working for some reason

ajgeiss0702OP•11/16/24, 3:44 AM

misleading, unhelpful or just wrong error messages is probably my biggest gripe with cloudflare

Isaac McFadyen•11/16/24, 3:01 PM

The confusion there comes because Workers AI Whisper doesn't use OpenAI. It uses the OpenAI model but CF doesn't pay OpenAI for that (it's open-source) so they can run it much cheaper themselves.

simons2889•11/16/24, 6:28 PM

I compared the two models.
The worker AI feels average, over a second slower, and less accurate.

are there any updates on the cloudflare worker + baselime integration?

Kimitri•11/17/24, 3:41 AM

it's just impossible deploy Nextjs on workers with the free plan? I tried just create a new Nextjs project, setup it to deploy on workers and when I tried it says that the followings packages are too big, but the problem is that this packages is essentials packages like fetch from javascript
